METHOD AND APPARATUS FOR CODING IMAGE SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide an image signal encoding method and device capable of effectively encoding a video frame signal and improving data compression efficiency by using expansion-interpolation technique. SOLUTION: This video signal encoding device consists of 1st and 2nd encoding channels 100, 500 and an expansion-interpolation device 400 for generating a processing block expanded, in order to effectively encode the boundary part of an object in a video signal. The channel 100 is used for encoding the contour signal of an object, and the channel 500 is used for encoding a digital video signal in each block.
